Sample XML Labels
=================

A. Survey 3D Sample Label

This sample label is from the MAVEN SWEA Survey Rate 3D Electron Distributions 
Data Collection (LID=urn:nasa:pds:maven.swea.calibrated:data.svy_3d). The 
sample data product label is for the date 2016-02-08.

            This data file was processed using the SPICE MAVEN SCLK kernel
            MVN_SCLKSCET.00026.tsc. The clock correlation provided by this
            version is identical to the correlation provided by the latest
            archived kernel through 2016-02-12T14:58:56.379 (5.0856120456300E+08
            TDT). After that time the spacecraft clock drift rate in this SCLK 
            kernel has been predicted and, when used, resulted in timing errors
            relative to the latest archive SCLK kernel.

            This data file was processed using the SPICE MAVEN SCLK kernel
            MVN_SCLKSCET.00026.tsc. The clock correlation provided by this
            version is identical to the correlation provided by the latest
            archived kernel through 2016-02-12T14:58:56.379 (5.0856120456300E+08
            TDT). After that time the spacecraft clock drift rate in this SCLK 
            kernel has been predicted and, when used, resulted in timing errors
            relative to the latest archive SCLK kernel.

            This data file was processed using the SPICE MAVEN SCLK kernel
            MVN_SCLKSCET.00026.tsc. The clock correlation provided by this
            version is identical to the correlation provided by the latest
            archived kernel through 2016-02-12T14:58:56.379 (5.0856120456300E+08
            TDT). After that time the spacecraft clock drift rate in this SCLK 
            kernel has been predicted and, when used, resulted in timing errors
            relative to the latest archive SCLK kernel.

            This data file was processed using the SPICE MAVEN SCLK kernel
            MVN_SCLKSCET.00026.tsc. The clock correlation provided by this
            version is identical to the correlation provided by the latest
            archived kernel through 2016-02-12T14:58:56.379 (5.0856120456300E+08
            TDT). After that time the spacecraft clock drift rate in this SCLK 
            kernel has been predicted and, when used, resulted in timing errors
            relative to the latest archive SCLK kernel.

            This data file was processed using the SPICE MAVEN SCLK kernel
            MVN_SCLKSCET.00026.tsc. The clock correlation provided by this
            version is identical to the correlation provided by the latest
            archived kernel through 2016-02-12T14:58:56.379 (5.0856120456300E+08
            TDT). After that time the spacecraft clock drift rate in this SCLK 
            kernel has been predicted and, when used, resulted in timing errors
            relative to the latest archive SCLK kernel.

2.6       Archive Omnidirectional Energy Spectra Sample Label

No sample Archive Omnidirectional Energy Spectra sample label is provided at 
this time. The SWEA arc_spec data product was defined before launch, however 
through the time when this document was generated SWEA has not been configured 
to produce arc_spec. Svy_spec is more than sufficient and the SWEA team has 
chosen to use the archive (burst) system for the higher resolution PAD and 3D 
data. The SWEA team does not expect to ever produce arc_spec.
